What is CloudLinux?

Reaching a high level of stability can be difficult, sometimes unachievable, for many shared hosting companies. Sudden resource usage spikes, increases in traffic, and hacker attacks are some of the problems system administrators cope with everyday. For years, this has been accepted as a cost of doing business. It costs money, it costs time and, more importantly, it costs customer trust. Therefore, it is time to consider changing the underlying OS to eliminate those costs.

CloudLinux was released to the market in 2010. Today, it is a must-have for any web host who cares about stability, security, and churn. It is used by more than 2,000 hosting companies on 20,000+ servers. CloudLinux is interchangeable with CentOS so any SysAdmin will feel right at home. Yet, it was specifically optimized for shared hosting. Web hosts that use CloudLinux report higher uptime, significant improvements in density (as much as 5x), 4x decrease in number of reboots, and 10x decrease in number of account suspension they have to perform. It has also produced a significant decrease in churn for a number of customers.

The software specifically made for web hosts running cPanel control panel with multiple accounts. If you are a shared host, or a design company that has to host sites on behalf of the client – CloudLinux is your friend.

CloudLinux + cPanel =

Improved stability by limiting the resources any single user can consume In shared hosting, the most common reason for downtime is a single account slowing down other accounts on the server. Using cPanel & WHM software with CloudLinux utilizes innovative Lightweight Virtual Environment (LVE) technology, improving the density and stability of your shared hosting environment for all tenants.

Advanced server security With unique CageFS technology, CloudLinux encapsulates each customer, preventing users from seeing each other and viewing sensitive information. It also prevents a large number of attacks, including most privilege escalation and information disclosure attacks.

Increased server efficiency By monitoring and containing resource spikes, CloudLinux eliminates the need to leave server resources idle, providing you with the ability to host twice as many accounts on your cPanel & WHM server.

Multiple PHP versions Using CloudLinux together with cPanel & WHM software gives your customers with the flexibility to choose the PHP version that they need. This includes versions 4.4, 5.2, 5.3, 5.4, and 5.5 as well as more than 50 PHP extensions and the ability to adjust php.ini settings.

Hardened kernel The shared hosting environment is unlike any other and the CloudLinux kernel takes that into account. It can protect against symlink attacks and trace exploits, while restricting the visibility of ProcFS to only what is necessary — making your cPanel & WHM servers more secure.

Admin interface within cPanel & WHM software to easily manage account usage Within cPanel & WHM, CloudLinux gives you and your clients the visibility and accessibility to see and control the exact resource usage of each website.
